'ro ALL WHoM IT MAY oo NcERN:

Be it known that I, CHARLES A. BABCOCK, of Frankfort, in the county of Herkimer, and State of New York, have invented certain new and useful Improvements in lhifile'lree Hooks; and I do herebydeclare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this'specification,- in which.

Figure l'is a side elevation, i

Figure 2 a plan view, and Y Figure 3 a perspective viewioi' my hook.-

To enable others skilled in the art to make and use my invention, I will proceed tedescribe its construction and operation. Y

A represents a cylipderor end-piece, which is excavated or made hollow to allow it to'be iittedor inserted on the end of thewhiiile-tree, and fastened thereto in the ordinary way.` ais a circular projection or ridge placed or Amade on the outerv portion of the cylinder A, a. suitable distance from projection IJ, said projection b being secured at the outer end of cylinder A, and made as seenvin ig.3. c represents a groove or slot cut in the circular projection a, large and deep enough to admit the end ofthe hook to pass when it is desired to lock said hook. It will be observed that this groove 'or slot is cut or made directly opposite to the projection b, the object of which is to'lock'or unlock the hook when required. B is the hook linked or hinged to the side of the cyli-nder-9pposite projection b by means of a staple or eye, e. v' lhis hook is so looped at its-inner end that it vwill fit down over the cap of the cylinder, and also over its projection b, thus allowing the end' of the hook to pass through the slot c in order to fasten or lock said hook.

In-the operation of'this invention, it will only be necessary to have the cylinder in proper position on the whille-tree. The end of the trace is then inserted in the hookan'd said hook pressed down over the cylinder and its projection, and at the same time through the groove c, and slipped around said cylinder, thus securing the trace and locking the hook in position.

Having thus described my invention, whutl' clamas new, and desire to secure by Letters Patent, is-

1. The cylinder A, provided with projections a and b and groove or slot c, substantially as and for the purpose seit forth.

2. In combination with theabove, I claim the hook B, substantially as and for the purpose specified.

In testimony that I 'claiinthe `foregoing as my own, I aiix my signature, in presence of two witnesses.
